RSS

This tag explains how RSS works as a syndication format, and how tools like PostRSS use it as the trigger for automated social media posting. An RSS feed is a structured XML document listing a site's recent items, each with a title, link, publish date, and usually a summary and image; PostRSS reads this document on a schedule, every 5 minutes on standard plans, to detect new content. Understanding the format helps explain why some feed items publish cleanly to social media and others don't: missing titles, broken image links, or malformed feed structure all affect the resulting automated post. This tag is a good starting point for readers new to RSS as a concept, before moving to more specific feed-setup or platform guides. RSS itself predates most modern social platforms by over a decade, and remains the most reliable, machine-readable way for a website to announce its own updates, which is why automation tools continue to rely on it.
